Wholock- Goodbye~ Regeneration

One day I was watching some Doctor Who Confidential, when I thought of this. I'm a fan of both Sherlock and Doctor Who, and I knew quite a few pieces of art that contained the crossover of Wholock. So I thought, what if Sherlock, when he was 'dying', if he regenerated? I've watched to the end of Sherlock season 2 so I know what actually happens, but the fandom can come up with a whole lot of stuff too.
